Installation Directions (Main Discharge Chute 133-5590 + Upper Deflector Procedure Style) Hilly Ridge Sales & Service tech tip: Take 2–3 quick photos of the discharge chute rotation gear & bracket components, latch components, deflector linkage & control cable routing before you take anything apart. It makes reassembly faster and prevents confusion. Safety / Prep Park on a flat surface. Shut engine off, remove key, and disconnect the spark plug wire. Let all moving parts stop completely. Wear gloves—sharp edges and packed ice can cut. Clean packed snow/ice from the chute base, ring, and gear area before disassembly. Take a visual Documentation of Parts (a quick phone photo helps). A) Remove the Existing Chute Assembly Rotate the chute to a centered position so the gear mesh is easy to re-align later. Remove the chute cover (if equipped) to access the rotation gear/drive components. Disconnect the chute latch spring/lock mechanism and Deflector Control Cable (if applicable) so the chute can lift off cleanly. Remove the chute mounting fasteners evenly around the ring/base. Keep hardware grouped for re-use if it’s in good shape. Lift the chute off the ring/base. If it’s stuck, gently rock it—don’t pry hard on plastic components. B) Transfer / Install the Upper Discharge Chute Deflector (131-5915-Style Steps Integrated) * If your deflector (upper flap) and linkage are being reused, transfer them to the new chute now. If you are replacing the deflector components, install them onto the new chute before mounting the chute to the unit. Remove the deflector pivot hardware (Commonly a Torsion Spring & Pivot Pin - May Be a Clip-in Place or Retained with a Bolt Depending on Model) and lift the deflector off the chute. Inspect the pivot holes and the deflector edges. Replace any cracked, egg-shaped, or worn components to prevent slop and binding. Install the deflector onto the new chute and start the pivot fastener by hand. Reinstall the torsion/return spring in the same orientation as removed (spring legs seated correctly so the deflector returns and holds position). Reconnect the deflector pivot rod/linkage. Make sure it moves smoothly through full up/down travel without rubbing. Do not overtighten pivot hardware—tighten only until the deflector moves freely without side-to-side wobble. NOTE: For Personalized Direction for Each Individual Discharge Chute Deflector Type Refer to Disassembly and Assembly Direction associated to each individual Discharge Chute Part Numbers 119-7629 & 131-5915. C) Install the New Main Discharge Chute (133-5590) to the Lower Ring / Base Inspect the chute ring/base and clean debris from the mating surfaces. Set the new chute onto the ring/base, ensuring it seats fully and evenly all the way around. Install mounting fasteners finger-tight first, then snug them gradually in a crisscross pattern (even clamping helps prevent distortion and stiff rotation). Reinstall the chute rotation gear components and confirm proper gear mesh (no skipping teeth, no excessive tight spots). Reconnect the chute latch mechanism and spring (if equipped). Verify the latch locks and releases positively. D) Final Checks & Adjustments Rotate the chute fully left and fully right. It should turn smoothly without binding. Run the deflector fully up and fully down. Confirm the rod/linkage does not bind and the deflector holds its position. If rotation is stiff: loosen chute mounting fasteners slightly, re-center the chute on the ring, and retighten evenly. Reconnect the spark plug wire and do a quick functional test at idle speed only. Hilly Ridge Sales & Service tech tip: If the old chute failed from impact, also inspect the ring, gear teeth, latch, and mounting brackets for hidden cracks or bends—those issues can cause premature failure or hard chute rotation.
